The features of perfect competition is given below.

• large number of buyers and sellers
• homogeneous product
• free entry and exit
• the firm is a price maker

Question 24.
The Price and Revenue Schedule of a monopoly firm is given below
a) Complete the Table
b) Draw AR and MR Curve

a)

b)

Question 25.
Some macro economic variables are given below.

 Item Rs. (in crores) Depreciation 200 Final Consumption Expenditure 2400 Investment Expenditure 1750 Export 430 Import 450 Government Expenditure 1000 Net Factor Income from Aborad 600 Net Indirect Tax 200

a) Calculate GDPMP by using expenditure method.
b) Calculate National Income (NNPFC)
a) GDPMP = AD = C + I + G + (x – m)
= 2400 + 1750 + 1000 + (430 – 450)
= 5150 + (-20)
= 5150 – 20 = 5130

b) National Income = NNPFC
GNPMP = GDPNP + NFIA
= 5130 + 600 = 5730
NNPMP = GNPMP – Depreciation
= 5730-200 = 5530
NNPFC = NNPMP – Net Indirect Taxes
= 5530 – 200 = 5330

Question 26.
Mr. Shaji is a resident Indian Working in the USA. He decided to purchase the following items when he returns to India. He wants to compare the prices of commodities in the USA and India.

 Item Price in USA (Dollar) Price in India (Rs) Shirt 20 500 Laptop 500 30000 Leather Bag 50 2500

When Exchange Rate is One dollar = Rs. 50
a) Which Economic Concept will Mr. Shaji use to compare the prices? Write the equation.
b) From which country purchasing these commodities will be more profitable for Mr. Shaji?
a) Real Exchange Rate = $$\frac{e p f}{p}$$

b) Shirt = $$\frac{e p f}{p}=\frac{50 \times 20}{500}=\frac{1000}{500}$$ = 2 means shirt is expensive in the US.
Laptop = $$\frac{e p f}{p}=\frac{50 \times 500}{3000}=\frac{25000}{3000}$$ = 0.53
Means laptop is cheaper in the US, hence better to buy from there.
Leather Belt = $$\frac{e p f}{p}$$
= $$\frac{50 \times 50}{2500}=\frac{2500}{2500}$$
means leather belt costs exactly same in both countries.

When the government increases its revenue expenditure the AD will shift upward. The equilibrium changes from e to e1 The level of revenue increases.

b) When the government increases lumpsum tax the AD shifts downward. Equilibrium changes from e to e1. The level of income falls from y to y1.

Question 29.
A law says that if we keep increasing the employment of a factor input, other inputs fixed, the marginal product initially rises, after reaching a certain level of employment of input, it starts falling.
a) Identify the law.
b) Diagrammatically explain the Law by using Total Product Curve, Average Product Curve and Marginal Product curve.
c) State the relationships between MP and AP.
a) A law of variable proportion

b) The law states that if we keep increasing the employment an input with other inputs fixed initially the total product will rise fast, then will reach a point where the total product starts falling. According to the law the marginal product of an input initially rises and then after a certain level of employment it starts falling.
